Title: Method of measuring interference effect on glass fiber transmission links and transmission system
Inventor: BUELOW HENNING
IPC: H04B10/2569
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To simply measure the characteristics (polarization mode dispersion) of a transmitting link by transmitting two signals at different frequencies over the transmission link and evaluating the signals from a frequency corresponding to the frequency difference between these signals. SOLUTION: A light source 1 is connected to a transmission link 7 to receive two signals at different frequencies, i.e., has a laser 2 for generating two optical carriers having a frequency spacing of e.g. 60 GHz by the both side band modulation. At a reception side a photodiode 8 generates electric carriers of 60 GHz by the coherent detection, the polarizing condition of the electric field with two optical carriers varies due to the polarization mode dispersion, hence the power detected by a receiver 9 also varies, resulting in that the power of the carrier frequency of 60 GHz is a measured value showing the polarization mode dispersion over the transmission link 7 and hence the characteristics of a glass fiber link can be analyzed by measuring the instantaneous polarization mode dispersion of the transmission link 7 by a simple measurement.

Inventor: TESHIGAHARA HITOSHI
IPC: H01L21/304
Filed: 1989-06-27
Abstract: PURPOSE:To remove contaminant and unnecessary material which are attached to the inside of a trench by compressing and pushing ice particles into the inside of the trench, melting the ice particles by heating, and drawing a treating liquid with said water. CONSTITUTION:Ice particles 8 whose diameters are less than the width of the opening of a trench T are deposited on the surface of a semiconductor wafer W in which the trench T is formed. The ice particles 8 are pushed into the trench T with a compressing plate 12. Thereafter, the semiconductor wafer W is heated, and the ice particles 8 in the trench T are melted. Since water is present in the trench T, the water and a treating liquid 2 undergo substitution when the treating liquid 2 is supplied on the surface of the semiconductor wafer W even if the width of the opening of the trench T is narrow. The treating liquid 2 is drawn with the water that is present in the inside. As a result, the treating liquid 2 can enter into the inside of the trench T. Thus, contaminate and the like which are attached to the inside of the trench T can be removed even if the width of the opening of the trench T is narrow.

Filed: 1995-06-30
Abstract: PURPOSE: To reduce the circumferential dimension of the spring bearing surface so as to improve the flexural rigidity of a ring piston at this part by arranging piston pawls and springs alternately one by one in a circumferential direction. CONSTITUTION: In a ring piston 14, piston pawls 14b and springs 22 are arranged alternately one by one in a circumferential direction, and one spring bearing surface 14c is provided with only one piston 22. The circumferential dimension of the spring bearing surface 14c is thereby small, and the flexural rigidity of the ring piston 14 at this part is large. Accordingly, even if the ring piston 14 is thin, the ring piston 14 is prevented from being deformed or damaged by bending stress applied to the ring piston at the part of the spring bearing surface 4c by the spring 22. Since a protrusion 14d for supporting the spring 22 is provided in the circumferential center position of the spring bearing surface 14c, bending stress is applied to the center position part, so that flexural rigidity can be further improved.

Title: Interference check system for robot and work
Inventor: YASU TAKAMI
IPC: B25J13/00
Filed: 1991-06-10
Abstract: PURPOSE:To attain an interference check system where the interference is previously checked in a relative shift state between a robot and a work in order to prevent the collision between them. CONSTITUTION:The surfaces of a robot and a work are covered and approximated by the polyhedrons. Then the shortest distance is calculated between the ridgeline of a polyhedron 41 covering the robot end the surface 42 of the polyhedron covering the work. Thus the interference is checked between the robot and the work. At the same time, it is decided whether the ridgeline of the polyhedron 41 is positioned or not on the entire surface in the moving direction of the robot. Then the interference is checked to only the ridges existing at the front side so that the processing data quantity is reduced. Thus the high speed and sure interference check is attained with high efficiency.

Title: Gas turbine stator blade
Inventor: ISOBE NOBUHIRO
IPC: F01D9/02
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce thermal stress generated in a member for achieving a long service life by machining a groove or a slit from a member surface to a depth direction and thereby absorbing deformation due to thermal expansion caused by the machining so as to reduce thermal stress and suppressing the growth of a generated crack. SOLUTION: The direction of a projection 4 for fixing a stator blade on a shroud is kept coincident with the rotational direction of a turbine. This projection 4 is also provided in an inner wall 3. A groove 5 parallel with a turbine axial direction is a groove for reducing thermal stress. The machining of the groove or slit 5 in a direction vertical to bending reduces bending rigidity. Since the bending direction is vertical to a crack, the groove 5 is machined in this case. Since the groove or slit 5 is provided in the cooled side of a member, the surface area of the cooled side is increased and the cooping strength of the member is thus increased. Thus, the thermal stress of the member is reduced, and the life of the stator blade is prolonged.
